Porting from Qtopia to Opie - how hard

Hello,

Several days ago CVS server on sourceforge became operational. This opened
sources of otrplayer (http://otrplayer.sf.net) - nice mp3 player for Qtopia.

I like the player for its capability to save playlist state and position in
mp3 file on exit. Other option (or lack of it) that I like, is that
otrplayer does not show ID3tags information. The ID3tags are useful, when
done right, but there are cases when one wants to disable them (not possible
in xmms).
For example, ID3tags can have international letters in some obscure windows
encoding. They also can be too long and hence - useless on small Zaurus
screen.

How hard will it be to port the program to Opie?
