SPRING and OSGI

I've been consulting with a small Java team that's implementing SPRING and OSGI

I could tell you what they are doing but then I'd have to shoot you, so let's just say they're doing neat stuff.

I haven't poked around any of those two technologies in some time, and wow! SPRING looks like a great library, and OSGI (which I have had very little exposure) expands on SPRING in some powerful ways.

I wonder if there is something similar available in OCaml? Sort of a dynamically-available, real-time-bindable, functionally-based, language-oriented coding environment?

They pay me by the syllable, folks. I'm not sure, but I think I just made enough for a new pocket-protector. (grin)
