I personally would like the ability to download all the pro apps dependant on whether my download period hasn't expired. What do I mean by this? My suggestion would be for UNA to offer a 6 months download period for e.g. $50. USD. Therefore as long as my download period hasn't expired I am able to download any or all of the Pro Apps. I might not renew my download plan every time it expires if I think I don't need all the updates. However, when there are upgrades, bug fixes, etc. in various apps I'll be sure to renew my download plan. Having said this, I might decide to renew my download plan once it expires as way of showing full support for UNA.
