[development] Distributing "bi-modal" Drupal modules

[Ken Winters]

While this might be entirely possible, what's the advantage?

It's not like you can just swap between D6 and D7 cores and not have  
problems.  You have to go through the proper upgrade path.

Since you can't just change versions, I highly recommend using proper  
source control branching instead of polluting your codebase.
