Well, there might be a way to do it.
There's a little-used feature called the Web Preview Window available  
in the Windows menu.
It has a drawer with options for filtering the current document  
through a shell script and then displaying the results.
You can have it run x.x number of seconds after and change.

I currently use it to live preview textile/markdown and do a live diff  
of my code with the saved version of it.

You could totally write a validation script that looks at the current  
scope to determine what validator to use.
Then the validator could output HTML with textmate links to the lines  
with the errors.

Here's my current live preview / live diff web preview script:

Please let me know what you come up with, this could be a very handy  
tool.
