AS Passport Wireless is equipeed with Twonky Media Server, you could give “Twonky Beam” a chance.
Found a thread here in the fourm:
Seems that “Twonky Beam” now is “Mediaplay”
“Twonky Beam” for Android is here (no clue why Japanese language appears here):
https://play.google.com/store/apps/details?id=com.pv.twonkybeam
Having Android, you can take a look at MediaHouse too,
https://play.google.com/store/apps/details?id=com.dbapp.android.mediahouse
Anyway, Twonky on the Passport Wireless is full dlna-certified Media Server, so all your dlna-capable devices will see your Passport Wireless as dlna media server.
BTW: most ebooks are heavily secured with DRM Digital Rights Management. I don’t think that you can “share” this type of media so easily.
