There is an option to use libcURL to read websites in the Tools module right now, instead of the old way using direct socket connection. I haven't looked into cURL myself yet, but using a dedicated library there should be several advantages.
There is one thing worrying me though.
For all people that can manage their own linux server there shouldn't be much trouble to install libcurl and the curl php extension. Even if it's not default for php, most extensions relying on a third-party library aren't.
EDIT: Ok, the php extension is in the full php download package, I guess you only need to enable it in php.ini and put the cURL libraries into the php directory. Haven't tried it though.
People running bebot under windows won't have heard about cURL most of the time. And expect for a few rare cases won't have it installed at all. Even if it is on the system it needs to be activated in php at configuration time, and most people under windows don't bother with that.
Which brings me to my point:
I'm not sure we should support something like that in the bebot releases. For many users it will be too much trouble to run it, on top of having to install mysql already.
But if enough people wish the support of modules like cURL we can keep it as an option.
If I missed some arguments please add them, too early in the morning
