use the HTC-IME modded keyboard. You can even go into keyboard settings and have it set for the enter key to serve as "send", or have it not do fullscreen edit mode in landscape (like my screenshot)
make your own skin here (make a login on his site, use hi res link, and v26 keyboard, enjoy), you can even make a pink one or one with a custom logo for your space bar lol
