Stuff to think about:
 - PCI DSS(Payment Card Industry Data Security Standards) QSA (Qualified Security Assessor)
 - NetFlow/IPFIX (Crannog/NetScout/Arbor) as networking/security is increasingly about context/relationships/visibility.
 - Normalization/baselining tools a la PeakFlow, SourceFireRNA 
 - Visualisation and Modelling (Opnet)
 - IDS/Rootkit detectors for virtualised environments.(Watch this space... BluePill/F-Secure )
 - Security Metrics(emerging/huge future as currently un-quantifiable!) and audit via Skybox / Algosec 
 - Digital Signage, MCAST/P2P distribution JOOST style.
 - Infrastructure/solutions to facilitate SoaS(Software-as-a-Service) e.g. Salesforce/Joomla/Atlassian(Confluence)/GoogleApps/Zimbra/Zoho, virtual offices whereby nodes act as client/cache/server and don't backup locally but more to Web Services akin to AWS(Amazon Web Services),S3,EC2. Managing a virtual customer's DNS and aggregating management of their services has potential?
 - Mobile and mobility gateways, 3G(HSDPAv2) vs WiMAx back-haul for project offices/satellite sites and SME/SOHO
 - Location based services and GIS(Geographic Information Systems)
 - Identity Management via OpenID/Cardspace(InfoCard) hosted services.
 - Thin clients (Neoware)
 - Fixed Mobile Convergence(Still a while off!) Engin / MyNetPhone / SIP/IAX/Asterisk
Web 2.0+ has as many solutions as problems, a new middleware-tier('internet-service-bus' if you will!). Businesses will increasingly want more audit/control and lower operational overheads and greater security via thin-client computing utilizing the browser as the platform of choice, also generating secure local host based flows for compliance and reporting. Thin clients and infinitely scalable distributed computing/storage is on the way. If you don't run the data-centre processing/storage nor have the power, you'll want to control the gateways/reporting/auditing/caching and own/re-sell/manage as much of the local infrastructure/bus and back-haul as possible!
Regulatory and compliance requirements will always have a perceivable effect, especially in the financial services sector.. but with breach disclosure laws on the way in Oz the security -> landscape/consulting/auditing/accountability/visibility aspects of networks/services are not going to allow organizations to keep their heads in the sand for much longer.
