That is a great idea and will do it today. Just let me know if we need developers license for listing at marketplace, we would like to get it, I definitely cant find more info on price page. We do all testing in private network, no public access.
I work for guys that finally made RADIUS plugin for Blesta. It uses BlissRADIUS server that is 10y in production and it already works with WHMCS. So anyone wanting to migrate to Blesta can have identical set of features. More info http://bulbsoft.com/product/blissembed/details.html
