Unfortunately no, eCart 5 does not have the ability to allow more than one credit card to be used for a single purchase. You would have to custom code something like this. 
OK. Then how would I accomplish this using your tools?
Would something like work?
Modifying the eCart auto-created checkout form so it has two (or more) billing addresses to accompany two (or more) distinct credit card sections.
On confirm page, add additional server behaviours, one for each potential credit card. Set billing & credit card fields uniquely for each credit card and its accompanying server behaviour.
Somehow link the amounts allocated to the server behaviors so that the item is split up between them. Whether it is split in half, or the user has a choice to allocate a value for the first, with the remainder being taken up by the second etc. behaviour(s).
Am I on the right lines? Your above answer was not really that helpful. I am not exactly a whizz programmer, but if given a general sense of direction maybe I can come up with something. So ... does that sound like a plan to you ... is there something I am missing? Your experience and the predictive knowledge that go with it to indicate any likely pitfalls would be appreciated.
I also cannot be the only person ever having wanted to do this, so maybe you could consider adding this as a feature for some future version.
Thank you very much for your help.
