Actually they've integrated this pretty well. While on the product info page, they end up linking to a flash designer - looks like from another site. (I've asked questions to get more detail) but it pops up in a light box type container and if you "save" the design, it asks you to login to your account. The saving or loading simply places info into the attribute text boxes but doesn't add the product to the cart. So then it ends up timing out cause it is a zen cart session when they take too long or else leave it and come back to add it to the cart later.
The cookie cart can be handy but not in this case. Also found another handy tool while looking for the plugin. I'm really wanting an RSS feed or something when another plugin gets added or changed. No way to keep with some of the nifty stuff that's appeared!
So I have to literally rethink this whole thing. Being able to save the info to a cookie would be a solution so I'll take a look at the cookie cart. I have not worked with cookies much at all before so right now it sounds daunting.
Getting this one thing done tho may in the end create a usable interface - I've had folks ask for something similar literally since day one! It is a commercial solution but we tried a number of them and this works pretty dang good.
Any other thoughts?
