Copy wallet to Electrum or Multibit? Is there a way to import my wallet from Bitcoin.org's client into the much lighter Multibit or Electrum?  The disk space &amp; bandwidth consumption (not exactly well presented to a beginner) quickly made it unfeasible on home computers.
Speaking as one of developers on MultiBit, it is not currently implemented at the time of writing (Dec 2011) but there are serious development efforts to consolidate the wallet file format to suit all major Bitcoin clients.

Expect to see this functionality in Q1 2012.
