How does the 100 Year Domain Service work?
Network Solutions will register your domain name for the maximum term available at the underlying domain registry and then, as long as your domain is registered with Network Solutions, we’ll add additional years to that registration on an annual basis, ensuring that your registration is always renewed until it has been registered to you for a total of 100 years of registration service from the date of your purchase.

What if I transfer my domain name to another registrar?
It is important to note that your pre-paid 100 Year Domain Service is provided exclusively by Network Solutions for you, and will terminate upon any transfer of your domain name to another registrar, with no refunds. The number of registration years that transfer to a new registrar will be the current term of the registration at the time of transfer, as reflected in WHOIS.

I do agree that long-term name delegations have consequences for successor operators if no funds to cover the obligation are transferred with the registry and the obligation.

I don't think, however, given how the contract is written, that this important point applies to .com like it did to .org, since the contracts basically guarantee .com to the current operator in perpetuity barring very unlikely misdeeds.
