if it has a functioning POSIX interface and working X11 implementation (or something else which GDK supports)Check this out: http://tiltos.com/drupal/node/16
I wanted to have a GIMP on haiku, so I decided to do something with that. There were two paths to achieve this goal. The first one was to port a GTK+ and then replace X11 calls from a GIMP with the Haiku's ones (complex task). The second one was to port X11 to the Haiku (easy task). I chose the second path for now. The GIMP on haiku is quite stable except the bug #283 , which also affects Abiword and Gnumeric.;)
Better people than us have produced better OS's than Haiku, only to watch them fall by the wayside. NeXTstepOnce again, Wikipedia is your friend: http://en.wikipedia.org/wiki/BeOS
Apple CEO Gil Amelio started negotiations to buy Be Inc., but negotiations stalled when Be CEO Jean-Louis Gassée wanted $200 million; Apple was unwilling to offer any more than $125 million. Apple’s board of directors decided NeXTSTEP was a better choice and purchased NeXT in 1996 for $429 million, bringing back Apple co-founder Steve Jobs.:|
I've managed to port Ardour to Cygwin and it was a relatively painless task - but only because someone else had already ported many of the technologies that Ardour relies on (such as gtk-x11, libsndfile, libfftw3 and various other things). If I'd had to port all those things myself (as would probably have been the case with Haiku) I'd have had a much bigger mountain to climb.That's why platform indipendency is a really important thing (which Ardour, unfortunally, don't have).
I have to say it again: Haiku port it’s not that important, but “getting rid” of 3rd party technologies would result in “portability easyness”.
"the beautiful chaos that is linux"The beautiful of linux is the openness, not the chaos. Haiku team has introduced a kind of hierarchy in the open source scene (for example you can't make a distro without permission), it's not the cathedral nor baazar, but "kibbutz" approach: http://homes.dico.unimi.it/~monga/lib/oss-icse04.pdf

Would love to see a good LA-2 sound-alike (don’t have to look like it, like the UAD plugins do) plugin for LADSPA/LV2
