[Mono-osx] General cross-platform issues and considerations

Does anybody knows of windows.forms apps running on osx at the moment
? In my opinion, a part from the left-to-right issue, the mono
Windows.Form implementation is very good on Linux and it is a good
option for porting windows apps, but to me it performs very bad on OS
X now and make apps unusable.
Given that the WF on OSX problems are mostly related to the carbon
driver, anyone has taken in consideration the option of providing a
X11 version of Managed Windows Form by pathching the X11 linux
driver, given that X11 must be present in any case? at least until a
working native driver will be written?
May be this an option? have already be taken into consideration ?
(sorry to repeat if this is the case)
