eeeeemmmmmmmm It is hard to answer because BPEL is very new and there were few knowledge about it. It reside on application server side, but as I remember from some explanation in IBM confernece you should just design your business process and don't think what happen inside.just use that BPEL'S lovely tools.
Oracle is promoting BPEL as the next BIG THING, so I wouldn't say there are few who know BPEL, but you may have better luck at an Oracle site. Where I work, they've been trying to develop a BPEL application -- and the wisest thing I've ever done is stay the heck away from it. I've never seen a more hellish and tortured development process. Bugs galore, endless calls to Oracle, a never-ending stream of expensive contractors coming through the door, money being shoveled into a bottomless pit... There's talk of a version 2 of this app, not that the first has ever worked in an end-to-end test, and I've already got a slogan for it: "Jesus wept". Can't you see the T-shirts?

I wanna to try BPEL in real action, but I have not got opportunity to use it in my projects. It's too small for BPEL. So ... I wanna take a part in a big project (which based on BPEL). And If anybody is intrested in help of newbey in BPEL just mail me Jeak110(at)ms(dot)tusur(dot)ru

Aside from the vendors who have something "BPEL-enabled" to sell, I see little enthusiasm and uptake in the market at large. My impression too is that it is early days, and that the jury on whether or not BPEL will become popular is still out. After all, we're seeing a significant backlash against the wave of WS standards being created, and BPEL operates on an even higher level of abstraction than most of the other standards.

Just an update on BPEL-hell. (Being Canadian, we also refer to it by its French name, Poubelle.) I've just come from a project meeting (Yes, I thought I wasn't on the project, but they're throwing developers onto it like we're firewood and this project is a witch they are trying to burn at the stake.) The amusing thing I wanted to relate is that apparently the project is considered a great success by the upper echelon, who never come within miles of it. But then I suppose if you were far enough from the WTC's ground zero, if would have looked like an organized exercise in urban renewel.
Again: if your supervisor comes your way with a BPEL project, run!
