If you're using vi you can do something like this:
nnoremap <c-u> viwU
To use it just type the word in lowercase, hover your cursor over any letter in the word, and press Ctrl-U to highlight it.
Looks like they're watching. It had been like that for a couple weeks and still was up until the time I posted.
Here's one example we saw recently in new york going from the 116th/Columbia stop to 12 St Marks Place. Google's result: http://i.imgur.com/8zpbY.png Our result: http://i.imgur.com/gpDu5.png & http://i.imgur.com/8hvrs.png
Currently we don't have an app for muni, though it's something we're working towards. There are some nice apps for Muni that have real-time arrivals but lack routing. Transporter & Routsey are probably the two best.
Co-Founder of Embark here (letsembark.com). We have apps for 12 systems, mostly in the US (BART, Caltrain, NYC, LIRR, MNR, NJT, DC Metro, Philly, CTA, Metra, Boston & London Tube). We also integrate with iOS 6 maps, so our apps should show up for you if they're relevant. In my subjective opinion, it's a way better experience than a google maps web view.
EDIT: Looks like my co-founder David beat me to the punch
