I talked about it to the owner of the store I bring mine.
He said he used to do it for a while but stopped because it was too cumbersome and expensive.
Temperature and time controls are a lot more exacting than with printfilm (even C41). A temperature flux of a tenth of a degree over 15 minutes or so can be disastrous, and the temperature has to be set far more precisely too.
In all, only very expensive equipment can maintain the environment needed for proper processing of E6 film.

Well for 18 months or so I did all my E6 (Sensia) processing. With currently available kits, it is a fairly mechanistic process, you just have to follow the instructions precisely as to time and temperature.
On the plus side it cut my processing costs in half, meant I could get important shots processed quickly, and allowed me to push or pull film as required. On the down side, it takes quite a bit of time.
I think the difficulty of temperature control is a bit overplayed by Jwenting - though I appreciate he is simply relaying what he was told - any instructions I have read require temperature control to within .25 degree, but only for the first developer (its a 3 stage process) which takes 6 -7 minutes. While temperature control is also important for the next 2 processes, variations of .5 degree are OK.
Furthermore, if you get the time temperature slightly wrong all that will happen is possibly a slight colour cast and less than perfect density (but slight exposure errors could cause this as well) - if you intend to scan the slides, these are all easily corrected.
As to facilities - all my processing was done in the kitchen sink. All you really need are a very accurat thermometer and a water bath at the right temperature to sit the tank in.
Is it worth it? Only if you really need to cut processing costs and/or need a quick turn around after a shoot. The processes eats up about 30min. of your time per film - what is that 30 min. worth to you? There is no element of fun or creativity involved.
It suited me because a) I had the equipment anyway for B&W work and b) E6 processing locally was both expensive and took 3-5 days.
As for examples, any of my Sensia shots in the last 18 months were home processed.

Very interesting Colin! I am currently taking classes at the local University, and I work in the darkroom quite a bit, but I am learning everything about BW photography now, want to get into color and E-6 processing soon! Slides have to opened up in total darkness to, am I correct? Since we are working with positives, I thought it might be different.
Colin, what is the development cost approximately for one roll, if you do it your self?

Dimitry - slide film must be loaded into the tank in absolute darkness. Once in the tank and the lid on (double check - the lid IS on), you can work in normal light - you won't see the film again until after you have finished fixing.
Costs - well I'm not sure what prices you'll have to pay, but over here a Photocolor E6 processing kit costs Stg.14.99 (=US $22) which used carefully will process 6 films.
If you have developed rolls of B&W film, you'll find the process very similar - just 1 extra chemical stage (colour development). Of course, don't use anything important for your first try! And do read the instructions that come with the kit. Then read them again. And follow them to the letter.

Any film (movie film, slides, APS etc...) needs to be loaded in the closet. Just because slides are "positives" doesn't mean the chemical reaction doesn't work off the same principal (the catalyst is light, blah blah blah).
I've never tried doing slides myself, I've done BW before and it's fairly redundant...but with any color process, the temperature is very important. Sure, keeping temperature within 0.25 degrees +/- sounds easy, but when you've got the stuff in the tank, it can be much harder than it seems. If you're gonna do it, practice with temperature control for a LONG time before you start mixing chemicals.
