Gives you a couple of features:

1. There are LPV approaches which have vertical guidance and DH's
a bit higher than ILS's (I think the lowest I've seen is 300').

Check your own backyard! Here's a few in the NoVA area...

RMN is 254 (http://204.108.4.16/d-tpp/0612/09743R33.PDF)
JYO is 258 (http://204.108.4.16/d-tpp/0612/05288R17.PDF)
HEF is 298 (http://204.108.4.16/d-tpp/0612/05326R16L.PDF)

Now put that GNS 480 to work!
