I understood the value of LinkExchange in the geocities Era - everyone was online because you "had to be" but there were no clear monetization strategies. With page impressions as sole KPI it didn't hurt to get a few more by joining some ad-ring-system.
Nowadays the line between publishers (many impressions, put stuff online and monetize via ads) and advertisers (fewer impressions, everyone monetizing in some other way, no matter if they actually use online ads or not) seems quite clear cut. So not really seeing who would use this tbh.
I'll give it a shot. but I'm just not sure what size of ads I'm supposed to upload. Also, when I go to upload it, it assumes I have the precise ad size.
1.You upload your ad and it's shown on other Adtree users' websites.
2. Your ad is shown as often as possible on only relevant websites.
3. Right now, I do. With enough users the network could be monetized by charging monthly to advertise (without having to place an ad on your own site).

Good luck with your project though!
