Funding development: reasonable extra cost to run a VPS with TurnKey Linux?

Should TKL produce a new 'legacy' version (based on 8.04.4) alongside the new version (based on 10.04)?

I have just been doing a little reading and noticed that Ubuntu has recently been updated to 8.04.4 (announcement, release notes). I know there has been discussion and Liraz and Alon have confirmed that the next release of TKL will be based on 10.04, however as 8.04 has support until 2013 is there any plan to do a final TKL 'legacy' release based on 8.04.4 alongside the new releases?

Would you prefer virtual appliances based on Ubuntu or Debian?
