You aren't required to submit patches even under the GPL.  If I make
changes and don't distribute them then I have no requirement to reveal
my changes to the bioperl source code.  Also the GPL does not require
that the code be made freely available to all, just that users of GPL'd
software can request the source from the vendor/distributor and should
not find lots of little hoops to jump through to get it.  You can even
charge to get access if that charge is to cover the cost of the expense
to get it (such as the cost of a cd + mail delivery charge).
