I had never heard of them till the Shire deal a little bit ago. Haven't sat down and done any research. Now that they've dropped from the Shire announcement may be a good time. It appears that they have a big library (I thought I saw 40,0000 somewhere) and with multiplatform capabilities I wonder if more collaborations are likely.
I'm tempted to pick them in my charity portfolio if nothing else would make me keep an eye on them .
