There's currently a limited amount of transactions per block, this limit can be changed. There's certain stuff in place to give bigger transactions, older transactions and transactions with higher fee's precedence. That should kill the possibility to truly DoS the network, although it's possible to get blocks filled all the time, possibly forever. It's also possible to DoS certain nodes, although the network will not likely suffer from it. After sifting through all of this stuff the network seems quite inherently robust. The only thing I worry about is when the amount of transactions become too great for any single PC to manage, since a large part of the work is done everywhere. Then all those pc's'll have to sync up, it's a data nightmare.
Back in the beginning I criticized the scalability of the bitcoin architecture. Much, however, has changed since then. I doubt that those particular criticisms are still applicable.
