Getting VDSL Soon

Just got a letter this morning saying that DiggiNet will soon install intranet in my appartment with the oppitunity to get VDSL for a low price and later on IP phone and IP TV.
I got ADSL at the moment through cybercity wich is expensive,
499 danish crowns for a 1024/256 Kbit/s connections.

With DiggiNet i can get following connections:
2Mbit/2Mbit for 129 kr. each month
4Mbit/4Mbit for 229 kr. each month
6Mbit/6Mbit for 329 kr. each month
8Mbit/8Mbit for 429 kr. each month
10Mbit/10Mbit for 529 kr. each month
12Mbit/12Mbit for 629 kr. each month
14Mbit/14Mbit for 729 kr. each month

BUT:
Can Digginet's new owner/staff deliver a stable connection ?
Will i be able to control wan ports if i buy an IP ?
