Hello Bitcointalk Forum

I'm thinking about setting up a Bitcoin Exchange. I have located an open source BTC Trade Engine known as "Intersango" on github.

I'm just wondering if there are any alternatives to "Intersango" or is everyone else keeping their trade engines/backend code a closely guarded secret.?

Eventually we will be coding our own custom trade engine within NODE. But were thinking we would use something Open Source at first to speed things along and for reference when coding our own.

Any help would be appreciated .

Note: Our exchange is not designed to compete with BTC-E, MT-Gox etc etc...
