It is at least as good a candidate as the ParameterParser. I think
DynamicURI should be made an interface. DynamicURI/ParameterParser
paired implementations could then be used to alter the
uri format that we currently use. Not that I feel our implementation
needs improvement per se, but I have seen others such as what's in Tea
that might be of interest.

It might be worth exploring, but I can not say immediately that it will
lead to something workable in a general sense. There are potentially a
lot of other Object.toString() operations occuring during a velocity/jsp
template parsing, so it would find most of its benefit in applications
with not so much dynamic content, which are likely to not need the
efficiency. Of course you could carry this on to other Objects as
well. So again it is worth a look.
