Well... Django's template system works for any text format, so yes,
you could takes that text, compiled it as a template, then render the
template passing it the needed context. Since this might a bit heavy
on processing, you may want to do cache the result in the database
instead of recomputing the whole damn thing on each and every
display...

Why reinvent the wheel ? Django's template system already has a
parser. Now if you don't want to use the above solution, you could
also use a more Textile-like syntax (to be invented...), then use a
simple regexp in your filter to replace this syntax with the
appropriate dynamically generated html snippet.
My 2 cents...
