Hi. This post is more directed to the devs.
I have come across this on the internet:
I believe someone made this app for Android mimicking windows Live Messenger. It had this name previously but I guess he changed it because of Google play policy.
I don’t know what server is holding this app. I don’t trust a random Dev around the internet, even more coming from Brazil.
My point is, why not do a similar app to work with escargot server?
Did you realise that the video you link is in spanish and Brazil language is portuguese?
Edit: Mercury seems pretty reasonable as making the mobile msn experience happen again.
I had the official microsoft Windows Live Messenger app for iOS and i should say that mercury is pretty good.
