As anticipated, I'm leaving for the week. The trip was already planned and I regret not being able to posticipate, given the enthusiasm and flow of ideas that everyone here is contributing to creating. I hope I'll be able to check email and write some code during the week. (That one I find especially important: software is a flexible thing but ideas are even more flexible and it's easy to get carried away and deal with them only. I'll have to remind myself to experiment as much and as soon as possible.) Enjoy and have fun hacking. :-) Massimiliano
