I ask the first question simply out of interest. If I know what it's being used for, then I know what it might useful to work on next. The second question is rather more mercenary. I'm don't currently have any work, and it looks like my most recent client is going to default on my invoice. Frankly, I'm in a bit of hole. If you need any short term C++ and XML consulting - design/development/review/whatever - then I'd really like to hear from you.
Let me just emphasise that Arabica is free and will remain free. If you've got any questions, then don't be afraid to ask. By the same token, if you need a few days or weeks consultancy, then please get in touch.
