That's LGPL, GPL affects anything _linked_ to it ;(

LGPL would be fine, but GPL directly affects anything "linked" to/with
As GPL has never (AFAIK) been tested in court the whole discussion may
moot, but otherways you are in muddy waters if you use GPL'd modules and
don't make all your source available. It _may_ be possible to separate
your site into code, content and docs, but still at least whole source
is affected, perhaps contents too, depending on how you/RMS/judge sees

I can see only two reasons (except extortion) for not providing the code
1. extremely bad code and 2. some really nifty invention (here a patent
would serve you better anyway)
