This turned out to be a long answer:
Yes, I found a way -- actually a couple, yet not as straight foreward as I would prefer.
My general experience is that making html5-banners is painstakingly difficult if one do not have direct access to the hosting platform with upload availabilty -- in this case access to ADTECH-admin -- when testing the files. In my case I had to send these to a middleman at the newspapers, who couldn't bring me much more technical information in return other than telling me that the banners was rejected. Tough, slow, non-productive debugging as you might understand.
My path, being profoundly interrupted by conflicting (non)standards, lead the htm5-banners to be published in two ways at the end on two different online news services -- through ADTECH:
(1) A non-hype solution -- using Adobe Edge instead. I guess this is out of scope in your case, but I'll explain it further below.
(2) A hype-banner hosted by ADFORM, but delivered to ADTECH via a click-tag (text-file -- a string of data) outputted by ADFORMs online interface. The click tag was sendt to the newspaper and everything worked as a breeze. This is -- as far as I understand -- called "thirdparty delivery" and is quite common.
Concerning A: the online-news service received from me the edge-files (all files in same root, compressed graphics, etc.) adding a few lines of code in the header (unfortunately they didn't provide me the script) which worked fine with ADTECH.
My own professional ambition: developing new non-adobe design techniques and then in this case being oblighed to swap Hype for Edge for a short while, may be a disappointing challenge. But fortunately the Adobe Edge approach is quite comprehensive if you're an experienced Hype user.
This worked well with the first newspaper, but they couldn't use the same method (by unknown reasons) on the second one. Therefore I had to perform an alternative approach using Hype again:
Concerning B with Hype and via ADFORM: My luck was, that my client made a subscription at ADFORM where I had could upload, test and adjust the Hype output directly.
The requirements between ie. ADFORM, ADTECH and ADWORD are obviously different and incorporating the target platform online interface (on which you upload) is as deeply integrated part of the banner-production as the very coding (or the editor) making the files work. Therefore, above all, I strongly recommend access to the platform on which the banners is hosted.
This was my thoughts. I don't know if the abovementioned information is any help. The standards are unfortunately not yet at a level, where a html5-banner-file is of a consistent standard like flash-banners is a flash-banners.
Kind regards, Raaskot
Ps.: I guess Tumult Hype would be a(n even greater;)) killer app in the banner-business if export options was available targeting an array of prominent AD-hosting platforms directly.
