You can do both. Much of the decision is based on how complicated the rest
of your configuration is... Which you consider easier... And how good the
support staff is to implement changes going forward.
If you google on MPLS VPN Internet Access I'm sure you'll find a few
documents with sample configurations either way.
Keep in mind that most of us consult for these types of projects, so the
best design for you would involve some time (billable) to give a true
analysis and best decision in your case.
From a technical perspective both are feasible.

Subject: Help on MPLS Design
Dear Experts,
I am working on an MPLS core design for an ISP out here in Africa. I have
two types of customers that require internet access via the MPLS core.
1. MPLS VPN clients that connect via a 3800 CE router (PE - CE routing
protocol is OSPF) 2. Broadband clients that terminate on a Cisco 7609 (with
Cisco MWAM module configured as PDSN)
Below is a schematic topology of the MPLS design
Broadband _____________
Client -------------> | PDSN (7609) | Global routing
_________________________________________
|____________|
-------------------------------->|
|
|
|
|
|
| MPLS CLOUD | -------> INTERNET (VPN or GLOBAL)
_____________
|
| |
MPLS | Cisco 3800 | VRF VPN_A |
|
Client -----------------> | CE Router |
---------------------------------->|____________________________________
---------------------------------->|_____
|
|____________|
My Challenge however is how to configure the internet link whether in a VPN
or global routing table to give access for both broadband and MPLS clients.
Thank you for your advice
Gbenga
