Any possibil to run MJMD5/MJProxy directly on a smartphone?

[arcadia2uk]

I received my Sprint HTC EVO 4G yesterday. It's now rooted and the tethering is set-up.
This will allow me to cancel my broadband service since I now can connect to the 4G network through WiFi. However, I would then loose my MJ connection.
Is there a way to run MJMD5/MJProxy directly on the cellphone and then use i.e. sipdroid with the MJ service?
Has anyone tried?
Appreciate your input.
Thanks,

I'm presently using SipDroid via pbxes - sipsorcery - sipdroid - GV, some latency issues, but it works and ... it's free.
I'm currently on 3G, since Boston is not yet equipped with 4G, but hopefully it will be here shortly.
