Thanks to Andy (Mrspaceman) I could download a version of Bibliotheca working on the Edge.

For those of you using this app since a long time, can you tell me How I can connect the Edge to Calibre ??

For now I downloaded the Android SDK, added the Android Usb support and the device appear as Android when connected to the PC.
My calibre is configured with a "android tablet" but the option to send book to device are greyed.

Any Idea ?

Lobo.

EDIT: I finally connected my Edge to calibre (I forgot to mount the edge ... I like to be so stupid) unfortunately now I got the error message : "The application Bibliotheca (process uk.org.aspelllclark.bibliotheca) has stopped unexpectedly. please try again ...

Any Idea ??
