I can confirm however the excessive RAM usage. As many users have pointed out in the past about desktop Eddie's Mono dependency, you should build it as close to native as possible. It's not a big deal on desktop most of the time, but Android apps really shouldn't depend on something as fat as Mono, considering the available RAM on some phones.
We're glad to inform you that the RAM usage will decrease dramatically in the next release. Eddie footprint in RAM will not exceed 120 MB in total ("OpenVPN for Android" footprint is about 45 MB but then you need to consider OpenVPN which is 40 MB, for a total of 85 MB).
