PHPseclib/PEAR packages

Hey Jim,
There's a few PEAR packages and PHPseclib packages, some of which you
maintain, where there's source in two places.

What's your thoughts on perhaps:

   1. Superceeding http://pear.php.net/package/Math_BigInteger/ for
   phpseclib/Math_BigInteger (or whichever one is more maintained)
   2. Merging phpseclib/PHP_Compat with pear's PHP_Compat, or renaming
   3. Picking whichever one of http://pear.php.net/package/Net_SSH2 is
   better
   4. etc

?
And or swapping to github?

Previously, we've been keen to get everything in the PEAR svn repo; so that
QA changes can be applied if needed. However, now that github has arrived;
it's trivial to fork a repository and apply fixes - so the need for it to
"all be in PEAR" is far less if we're using github.
