Blocks in JLCP

Team,
    We need to come up with a good way for people to add new blocks to 
JLCP.  The way that PhpNuke does it I believe is they drop new blocks 
into the blocks directory of the installation.  There is most likely a 
simple config file that the block manager could then pick up.  Then the 
blocks are just HTML.  Anyone have any ideas on how we should handle 
this?  I think its a pretty important part of the whole scheme and 
having an easy way to add blocks will make JLCP that much more useful.
