yum development question

Reposting here as yum-devel seems overly quiet :( Is there a better place for 
yum devel questions (other than IRC?)

I'm working on CPacMan plugin for yum and so far I've had some success, but I 
am not quite sure whether I do things "right" so far. I've tweaked and twisted 
plugin to work under both RHEL5 (3.2.22) and RHEL6 (3.2.29) but at times I 
pretty much was beating it into submission.

I have simplified the code and pasted it here:

http://pastebin.com/NkUS6sb0

and would appreciate any feedback on it's quality/deficiencies... I am even 
willing to incorporate those changes and built simplified version of plugin 
once I'm done for "code snippets" section.

Brief outline of function:

plugin generates "pseudo-repo's" from a set of directories with RPM files. 
Locations of the repos and their contents are evaluated at run-time making 
them fairly dynamic (based on CPacMan rules, server class etc.). Packages are 
not meant to be installed on local machine either - I generate package 
manifest which can be used later to transfer files to a specific server and 
deployed there etc.

The main thing I'm interested in is whether I have properly implemented 
alternative repository/sack/package classes and whether I use them right, it's 
not about whether I should even attempt implementing features I'm interested 
in, which are: real-time _in-memory_ repo generation with all the goodness 
that comes with it ;)
