It is a different story if you need it both ways. So the scenario would 
be that when your editor generates well known ugly urls (by some 
definition), then these should automatically be changed into a 
different/nicer urls which then are returned to the users browser.
And then the rewriting can turn a nice'd url back into an ugly ditto 
once the user request the former.

I don't know if there is a way to alter the behaviour of <cms:link> (or 
rather core methods that handle the link transformation, as I assume it 
has to work for links entered into free text pages as well) without 
hacking the core. But it would certainly be a place this kind of magic 
could happen.

An alternative would be to handle this do as you've already suggested, 
i.e. to make a servlet filter. This should work but will add an overhead 
as you must parse the entire HTML file upon return from OpenCms. I am 
doing something similar with a filter that uses HTMLParser to parse the 
HTML from OpenCms and then alters the mailto-links - on modern hardware, 
working on pages with 500-1000 words and not particular complex HTML, 
the processing takes around 5 ms (plus whatever the filter mechanism 
uses 'outside' my code)
