Provide a few seats (15-25 users maybe) to MSDN subscribers
Currently, if an IT professional wants to either test Windows intune features or demo the features to potential customers, you have to sign up for a trial. Features change so often though, and (my customers anyway) often want to see what the product does and you end up signing up for multiple trials and rebuilding your lab/ PoC environment. My MSDN subscription includes $150 of Azure Credit, Intune should be there as well
Azure credits work differently than trial accounts, as you’ve seen.
One thing some people don’t realize is, we have no limit to the number of trial Intune tenants you can create for a single email address. Believe me, I’ve created dozens on my Microsoft email address. We don’t care how many you create, though there is a limit that each tenant can have only one trial account. I know, it means you have to keep recreating environments, but at least it lets you see what’s new any time you want.
If you are a Microsoft Partner, we have benefits that help with this. You can check out https://wpc.microsoft.com.

@Cathy: Given that MSDN subscriptions also include an Office 365 E3 developer license, surely something can be worked out. Additionally, since a single O365 tenant is restricted to a single E3 Dev subscription, you don't need to worry as much about limiting the trial accounts (since it's already handled).
Personally, I'd like to see InTune included in E3/E4, as much on the basis that such enterprise customers would likely benefit from device management.
