Waveboard is an app for the Mac (and coming soon for iPhone) that puts Google Wave into it’s own application window. Observant readers might recognise that this is not really all that different from using Fluid or Prism to create a stand-alone site-specific window. Links from the site suggest it is related to Mailplane, a similar concept for Gmail.

If however you don’t wish to worry about setting something like this up yourself you may wish to give it a try.

Waveboard is free software (at time of writing). Waveboard\
