Actually, please don't be quiet! When this was discussed some time ago, you mentioned Python as a solution, and my feeling was that if I write a piece and it uses some database connectivity, I don't really want to have to distribute a Python runtime, relevant Python SQL module, [py] and all the respective dependencies with it. I just (at most) want to include an external, and the databse library it uses. If I write a piece, I can't reasonably expect a performer to resolve all of this themselves - it needs to "just work". I also want to minimise as much as possible the number of discrete components in the system that could possibly go wrong. However, Lua seems a slightly different story, ([lua] doesn't require flext, and Lua is very lean) - I'm starting to be convinced by it. It might be interesting to recreate [psql] using lua and luasql, and see how it measures up in terms of portability, ease of distribution and performance. I just downloaded [lua], and luasql, and It certainly didn't take long to get these things working on a basic level.
